What are the quantitative measures used to give qualitative performance "scores?"

For gaming people, only super fast will do at any power cost.

For most other people, battery life dominates in the high end phone market in my opinion, as long calls are common, hectic days on road, but a dead phone is very very costly, so multi-day battery life in heavy use scenario is very important.

Other "performance" metrics are unclear to non-techies so perhaps someone can make them clearer in terms like "time to open email" or texting delays, whatever.

Does the "Relative performance" in the plot refer to computational performance/speed alone?

If so this analysis kinda sidestep the issue of power consumption. It was not the processor's computational speed that was in question. It was that Intel CPU had more or less the same performance at HALF the current drain/power.
